Hi Team,
I know this question has been asked zillion times but even after consulting Stack Overflow & other forum cant figure out the reason.
I have one var in my data-set names case age. This variable is numeric as:
class(SFDC$case_age)
"numeric"
however it throws this error:
(or 0-length row.names). As checked this only happens either there is some space at the end of the variable name, or there are no values whereas this is a numeric variable with no missing values and has a total of 5400 observations.
This var has a range from 0 to 240 in number of days for case variable hence i need to do a logarithm transformation & make it use in the model.
Please advice.
I need more information, when you get this error?
can you get the summary(SFDC$case_age) of your variable?
0-length row.names seems to point that you don't have names for the rows in your dataset
Hi Antonia,
Thanks for extending help. I got this error while doing the weight of evidence & information value technique. After researching the support document fofr WOE, your Y vector in all cases is to be categorical and it is numeric in my case hence making changes to this helped. I did it few hours back.
Hi,
I think you should trim your white spaces, e.g. with function trimws (from R 3.2.0 onwards)

"it throws this error" is not very informative; you need to say what throws the error (i.e., what command you issued that caused the error to happen).
